There was a waxing place in florida called lunch box (a waxing salon) I assume it is a non native english speaker named the business.

I would keep an eye ticket times, there was a lovely coffee shop just down the street from me but weekday mornings it would take 20 mins to get my morning coffee so I stopped going, I would go on weekends but making it simple for people to come get coffee they want and get out might do the trick.

I know an app to preorder might be a challenge but how about a “standing order” program, or a monthly subscription for a discount “one coffee a day for $x a month”
